3 The NAnt buildfile for doctools uses tasks that exist in NAnt 0.7.x,
4 and are not available in the version of NAnt (0.6) in our CVS tree.
5 As I really don't want to go through the hell of getting the newer version
6 of NAnt into our tree, the makefile and build files under doctools require
7 NAnt 0.7.x or greater to be in the path somewhere.
